Ok everyone, I'm going to help direct this discussion. To determine how to solve 'environmental effects' we first need to diagnose what's causing these effects. The shit things happening to our environment (the effects) are caused by something, so what's causing it? That's what we want to think about first when we think about this topic.
What do you think is causing these harmful environmental effects (keeping in mind that it's a multifaceted issue, there's more than one cause)? Is there one cause that is more impactful than the others? Finally, how can we mitigate the negative environmental effects associated with the cause you identified?
